.To aZZ whom it may concern.-

Be it known that we, EDWARD A. THIERY and CHARLES F. GRosELMIRE,citizens of the United States, residing at Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Articles of Jewelry and Methods of Ornamenting the Same,of which the following is a specification, reference being had thereinto the accompanying drawings, in which- Figure 1 is an elevation of asphere or ball with a seamless covering of metal. a vertical centralsection partly in perspective, showing the glass or crystal base and themetal covering. Fig. 3 is a view similar to Fig. 1, but with portions ofthe metallic covering cut away in ornamental design. Fig. 4 is alikeView of a different form of article, and Fig. 5 is a vertical centralsection of Fig. 3.

Our improvement relates to the ornamentation of articles of jewelry andthe method of ornamenting the same; and it consists in taking a base ofany desired form or configuration of transparent or translucentmaterial, coating the same by any of the known methods ofelectrodeposition, and afterward cutting away portions of the metalcovering, and, if desired, filling the designs cut out with somecontrasting metal.

In carrying out our invention, we take a base of glass, crystal, or anyother transparent or translucent substance, substantially of the form ofthe article to be produced, and deposit thereon by electrolysis themetal which is to form the seamless coating or covering. After asufficient quantity of metal has been deposited on the foundation orbase it is removed from the bath, and any fanciful design is formedthereon by means of a graver or on a wheel, thus exposing thetransparent or translucent background and producing a very pleasing andbeautiful effect.

In the drawings, a represents the base or form for the article; I), themetal covering, and c the cut-away portions forming the design. \Vesometimes fill in a portion or all of Fig. 2 is (No model.)

the cut-away portions with some contrasting metal, either in intaglio ofrelief. This can be readily done by coating the metal, after the designshave been cut out, with some nonconducting material, and a second timeexposing it in the bath.

The method we prefer in producing the seamless coating is to first coverthe transparent base with some suitable cement or size and applyingthereto before it is dry a bronze or metal powder, covering the ent-iresurface. After this coating is dry it is then electroplated, in anyusual or well-known manner, with gold, silver, or other metal or alloythat is capable of use in electro-deposition.

\Ve do not wish to limit our invention to any particular article, as itis well adapted for many articles of jewelry, such, for example, aschains, centers for brooches, ear-rings, heads of scarf and other pins,balls and knobs for bracelets, heads for canes and umbrellas, andindividual salts, &c.

By our invention we are enabled to produce many novel and pleasingeffects, as it will allow a light and beautiful tracery of gold orsilver, or both, over a transparent or translucentbackground, or even ona rich plain opaque color-as, a stone-for a background; and the articlethus produced can be manufactured of the precious metals at comparatively small cost.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. That improvement in the art of ornamenting articles of jewelry whichconsists in taking a base of crystal, glass, or analogous material ofthe form of the article to be produced, coating the same with metal byelectrolysis, and afterward cutting away suitable designs or tracingsthrough the metal, substantially as set forth.
